Explanation

The Sahahe Sitta (Six Authentic Books) are:

1. Sahih Bukhari
2. Sahih Muslim
3. Sunnan Tirmizi
4. Sunnan Abu Dawud
5. Jami' at-Tirmidhi (also known as Sunnan Tirmizi)
6. Sunnan Ibne Maja

Sahih Bukhari, Shamail Tirmizi is not among the Sahahe Sitta, as it is a different book written by Imam Tirmidhi.
